Are you ready for the season?

Safety First!

Check your avalanche equipment before every ski tour.

Does the Barryvox need new batteries? Are there any signs of damage or wear on the airbag?
Faultless operation of your avalanche equipment can be critical.

Check your Barryvox

Battery test Check your Barryvox before every ski tour, ideally before you leave home. To do this, switch the device on and note the display for the self-test and battery test. Weak batteries should be replaced immediately.

Damage and impurities Also check the device regularly for mechanical damage and impurities. In particular, make sure the battery contacts are clean and undamaged and the main switch is working correctly.

InconsistenciesIf you notice any inconsistencies during your check, it is essential to send your device to a Mammut Barryvox Service Center for further checks.

General inspection and maintenance

Check your airbag system before and after each use for signs of damage and wear, such as cracks in the housing, dents, visible threading, etc. Check the backpack, shoulder straps and hip belt for holes, tears and damaged seams. If the airbag happens to get wet, spread it out flat and leave it to dry. Before each use, check the airbag system as well to ensure it is fully functional.

To do this, follow the descriptions and illustrations below:

1. Installing the airbag system

Make sure the airbag system is installed correctly. To do this, open the zipper on the airbag balloon pocket from the center and slide the zipper pull to the right. The airbag system must be lying over the gray strap (red in the illustration).

2. Attach the airbag

Make sure the airbag is not attached the wrong way round.

3. Airbag system pocket

The airbag system pocket must be closed.

4. Deployment handle

The deployment handle must not be wound around the airbag system.

5. Airbag buckles

The four colored airbag buckles must be threaded through the appropriate loops from the bottom to the top.

6. Folding the airbag balloon

CAUTION: The airbag balloon must not be rolled up but must be folded for packing as follows. Check the airbag balloon for any holes or tears before folding.

7. Holding the airbag together

To hold the folded airbag together, close the hook and loop fastener over the airbag opening, carefully close the zipper and attach to the loop.

8. Deployment handle hook

The hook of the deployment handle must be pushed securely into the loop.

9. Cartridge pressure

Make sure the pressure in the cartridge is correct and that the cartridge is completely screwed in and secured.

Cartridge with manometer:at room temperature (20° C/68° F), the arrow must be in the green area.

Cartridge without manometer:the weight of the cartridge, without the protective cap, must be the same as the weight stated on the cartridge (+/- 5 g).

10. Cartridge assembly

Screw the cartridge all the way into the mechanism, secure it in the pocket using the hook and loop fastener and close the pocket.

CAUTION: The cartridge is completely screwed only when the black rubber seal is no longer visible.

11. Training deployment

Perform at least one training deployment each season. This will allow you to familiarize yourself with the system and ensure you can act quickly and intuitively in an emergency. To avoid having to fold the avalanche airbag again after a training deployment, you can use the trigger test tool to very easily carry out a test deployment without a pressure cartridge.

To do this, screw the trigger test tool all the way into the deployment mechanism.

Warning: The trigger test tool must not be overtightened.

12. Test deployment

Put the avalanche backpack on for the test. In order to make the situation as realistic as possible, we recommend wearing your skiing clothes during the test deployment. Deploying the airbag while wearing gloves is particularly good practice. To deploy the airbag, pull the deployment handle hard and decisively. After the test, unscrew the trigger test tool from the deployment mechanism again.
